QUANTITATIVE INTRAMOLECULAR FISSION IN OLIGOACENES, MATERIALS, AND METHODS OF USE THEREOF

The present invention provides soluble, stable singlet fission (SF) compounds, compositions, materials, methods of their use, and methods for their preparation that provide efficient intramolecular singlet fission (iSF) and multiple excitons. The SF compo

Improved synthesis of 1,2-bis(trimethylsilyl)benzenes using Rieke-magnesium or the entrainment method

1,2-Bis(trimethylsilyl)benzene is the key starting material for the synthesis of efficient benzyne precursors and certain luminescent π-conjugated materials. We now report that it can be conveniently prepared in tetrahydrofuran from 1,2-dibromobenzene, chlorotrimethylsilane, and either Rieke-magnesium (MgR) or magnesium turnings in the presence of 1,2-dibromoethane as an entrainer (Mge). The most important advantages of these new protocols over the currently best-established procedure (1,2-dichlorobenzene, chlorotrimethylsilane, magnesium turnings, hexamethylphosphoramide) lie in the milder reaction conditions (MgR: 0 °C, 2 h; Mge: room temperature, 30 min vs. 100 °C, 2 days) and in the fact that the cancerogenic solvent hexamethylphosphoramide is avoided. Moreover, the improved protocols are also applicable for the high-yield synthesis of 1,2,4,5-tetrakis(trimethylsilyl)benzene, 4-fluoro-1,2- bis(trimethylsilyl)benzene, 4-chloro-1,2-bis(trimethylsilyl)benzene, and 4,5-dichloro-1,2-bis(trimethylsilyl)benzene.

TITANIUM-CATALYZED DIELS-ALDER CYCLOADDITION OF CONJUGATED DIENES TO BIS(TRIMETHYLSILYL)ACETYLENE. 1,2-BIS(TRIMETHYLSILYL)CYCLOHEXA-1,4-DIENE, 1,2-BIS(TRIMETHYLSILYL)BENZENE, AND THEIR METHYL DERIVATIVES

The catalytic system Et2AlCl/TiCl4 induces Diels-Alder cycloaddition of bis(trimethylsilyl)acetylene to 1,3-butadiene, isoprene, 2,3-dimethyl-1,3-butadiene and (E)-1,3-pentadiene affording 1,2-bis(trimethylsilyl)cyclohexa-1,4-dienes in high yields.The cyclohexadienes are readily converted to the corresponding 1,2-bis(trimethylsilyl)benzenes upon heating to 240 deg C.Mass, infrared, 1H, 13C and 29Si NMR spectra of all the products obtained are reported and briefly discussed.The crowded character of aromatic compounds is reflected in their mass, 13C and 29Si NMR spectra.
